Final answer:
To determine the number of hamburgers and drinks that Indigo bought, we can use a system of equations.
Step-by-step explanation:
To determine the number of hamburgers and drinks that Indigo bought, we can use the following system of equations:
x: number of hamburgers
y: number of drinks
The total cost equation is:
5.50x + 2.25y = 42
The total number of hamburgers and drinks equation is:
x + y = 10
Now you can solve this system of equations to find the values of x and y.
